Power to move the Velite comes from Buick’s experimental twin-turbocharged, intercooled global V-6 engine. Four hundred horsepower and 400 lb.-ft. of torque are derived from its DOHC design and 3.6-liter displacement. The engine features fuel-saving variable valve timing technology, which is available on some of GM’s four-, five-, six- and eight-cylinder engines. Through the use of variable engine valve timing, valve lift and duration is continuously varied to improve fuel economy, horsepower and torque, while reducing emissions.
The V-6 is backed by a Hydra-Matic 6L80-E six-speed, rear-wheel-drive automatic transmission equipped with manual tap-shift gear selection. A pair of large, oval exhaust outlets provides an aural reminder that performance is very much a part of the vehicle’s character.
